A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 79.8 N at an angle of 28.0° above the horizontal. The box has a mass of 20.0 kg, and the coefficient of kinetic friction between box and floor is 0.300. (Indicate the direction with the sign of your answer.) (a) Find the acceleration of the...
A 5.00 kg box sits on a ramp that is inclined at 37.3 ∘ above the horizontal. The coefficient of kinetic friction between the box and the ramp is 0.27. What horizontal force is required to move the box up the incline with a constant acceleration of 4.30 m/s2 ?
You want to move some boxes down from a truck
using a ramp as support. One box has a mass of 50 kg. You are
holding it with a force F equal to 100 N. Friction is present and
the coefficient of kinetic friction is 0.2. The angle θ
= 30o
Determine the acceleration of the box.
A) zero
B) 2.8 m/s2 downward
C) 1.2 m/s2 downward
D) 3.0 m/s2 downward
F
Shortly after the start of a dogsled race, you find yourself pulling your supplies across the snow (those $#@*&%^*& sled dogs are in BIG trouble). You apply a force of 300 N to a rope that is attached to the front box at an angle of 20 degrees above the horizontal. Mass of the front box M=40Kg, mass of the black box m=30kg, and there is no friction between the boxes and the snow. A)Draw a free-body diagram of each...
